adding threading parameter as command line option

Is there a way to add the number of thread you want to use when running PAL Tool through a batch file (or via command line)? The options that are available to command line use is before the threading definition at the end of the GUI.

Yes, use the parameter -NumberOfThreads. This parameter is added to the Queue if you set the number of threads to be more than 1 and click the Back button to go back to the queue. Also, PAL.ps1 is a script, so if you are comfortable with Powershell, then
consider editing the script to see the parameters.
